Abstract

This study examines the implications of special items (SI) for future earnings using quarterly Korean data over the period from 2011 to 2014. Due to the lack of identification of SI in Korea, I choose several items as special items if they are material and non-recurring items following prior studies. Then I regressed seasonally-differenced future earnings on positive and negative SI and found that their effects on future earnings were different. While negative SI are explained by inter-period expense transfer, positive SI are not well-described by traditional prototypes. Next, I regressed seasonally-differenced future earnings on negative SI sub-types as they are heterogeneous in nature and have differing implications for future earnings. While PPE impairments and intangibles impairments are partly explained by the inter-period expense transfer, unspecified loss of other loss items are not. Interestingly, these effects are attenuated or disappear in the Kosdaq market when the markets are divided into the Kospi and Kosdaq markets.

본 연구는 국내 데이터를 이용하여 2011~2014년 간 특별손익항목이 미래 이익에 미치는 영향에 대해 연구하였다. 국내에서는 특별손익항목에 대한 분류가 없기 때문에 본 연구에서는 선행연구를 따라서 금액이 크고 비반복적으로 발생하는 항목을 특별손익항목으로 지정하고 분석하였다. 우선, 미래 이익과 양(+)과 음(-)의 특별손익항목간의 관계를 검토하는 회귀식을 통하여 본 연구에서는 양(+)과 음(-)의 특별손익항목이 미래 이익에 미치는 영향이 다름을 제시하였다. 음(-)의 특별손익항목은 기간 간 비용을 이전하는데 활용되어 미래 비용이 현재 비용으로 이전됨으로써 미래 이익을 증가시키는 데 기여하는 반면 양(+)의 특별손익항목은 전형적인 이론으로는 설명이 안 되는 비정형적인 특성을 보였다. 다음으로 본 연구에서는 음(-)의 특별손익항목을 세분화하여 미래 이익에 미치는 영향에 대해서 검토한 결과, 유형자산 손상차손과 무형자산 손상차손이 부분적으로 기간 간 비용 이전으로 설명이 가능한 데 반하여, 기타 비용항목은 기간 간 비용이전으로 설명되지 않는 것으로 나타났다. 마지막으로 주식시장을 코스피와 코스닥 시장으로 나눠서 검토했을 때, 코스닥시장에서는 기존의 결과들이 약화되거나 사라지는 것을 확인하였다.
